Trade-offs

The most common trade off people seem to make in university presentations is visuals for text. Less visuals, but more text.
Why is that?
I hear the argument: "Well you can review your slides better for recap." so often. I think this is harmful for a presentation. In university, the content should be presented in a visual way, so that concepts are understood more easily and academic literature becomes more engaging. For recap, there should be a handout with text, which can be reviewed easily.
How about that for a counterargument?
Let me know what you think.
Have a good week.
